Abstract
The utility model discloses a vacuum-pumping device of a plastic extruding machine, which comprises an exhaust port, a pressure gauge, an airflow adjusting valve and a vacuum pump; the exhaust port, the pressure gauge, the airflow adjusting valve and the vacuum pump are arranged on a charging barrel; a bulk separator filled with water is arranged between the exhaust port and the vacuum pump; a water inlet and a water outlet are formed on the side wall of the bulk separator; a first exhaust pipe communicated with the bulk separator and the exhaust port is arranged therebetween; and a second exhaust pipe communicated with the bulk separator and the vacuum pump is arranged therebetween. The vacuum-pumping device provided by the utility model adopts the structure that the bulk separator is additionally arranged between the vacuum pump and the exhaust port, gas exhausted from the exhaust port on the charging barrel passes through the bulk separator first; water is filled in the bulk separator; and the water inlet and the water outlet are formed on the side wall of the bulk separator. When the gas passes through the bulk separator, harmful impurities, dirt and the like in the gas can be resolved, absorbed or filtered through water. The bulk separator also can be used for preventing a medium in the vacuum pump from flowing backwards, so as to ensure stable product quality.
Description
Technical field
The utility model relates to the vacuum extractor of a kind of plastic extruder, particularly a kind of plastic extruder.
Background technology
Existing plastic extruder comprises head, vacuum extractor, barrel and feeding device; Vacuum extractor comprises exhaust outlet, Pressure gauge, barometric damper and the vavuum pump on the barrel; When plastic extruding forming; Because plastics are moisture, residual monomer, the lower boiling plasticizer of entrapped air, absorption and the oligomer that under forming temperature, can volatilize often, plastics that particularly some hydrophilic hygroscopicity are bigger or use the situation of aqueous plasticizer, the content of these compositions can be up to about 5%; These compositions are not as getting rid of; Can make the surperficial dim of goods, phenomenons such as hole, bubble, speckle occur, influence the outward appearance and the product quality of goods in the surface and the inside of goods.The effect of vavuum pump is with in the extrusion molding process, and the air of carrying secretly in the plastics, the moisture of absorption, lower boiling plasticizer and the low-molecular material that under forming temperature, can volatilize are got rid of, and improve the appearance and the quality of item of product.Vavuum pump all is to adopt oil, water or other fluid to serve as the working media of vavuum pump, multiple effect such as in vavuum pump, play cooling, sealing, lubricate.Not enough below existing structure exists: the working media of the vavuum pump pollution barrel that backflows, the material of extracting out in the production process can make the medium in the vavuum pump seriously rotten, causes vacuumizing not smooth, and the quality of product is affected.
The utility model content
The utility model technical problem to be solved is: the vacuum extractor that a kind of plastic extruder is provided; The vacuum extractor of this kind plastic extruder can be avoided in the vavuum pump working media pollution barrel that backflows; Can avoid the working media of vavuum pump rotten again, thereby can guarantee the steady quality of product.
Solve this technical problem; The technical scheme of the utility model is: a kind of vacuum extractor of plastic extruder; Comprise exhaust outlet, Pressure gauge, barometric damper and vavuum pump on the barrel; Be provided with water-filled volume separator between described exhaust outlet and the vavuum pump; Described volume separator sidewall has water inlet and delivery port, has the downtake pipe that is communicated with between described volume separator and the exhaust outlet, has the second exhaust pipe that is communicated with between described volume separator and the vavuum pump.
Described Pressure gauge and barometric damper are arranged on the downtake pipe.
Described downtake pipe and exhaust outlet removably connect.
Described second exhaust pipe and vavuum pump removably connect.
The vacuum extractor of a kind of plastic extruder of the utility model adopts such structure; Between vavuum pump and exhaust outlet, increase a volume separator; The gas that exhaust outlet from barrel is discharged at first passes through the volume separator; In this volume separator water is housed, water inlet and delivery port are arranged on the sidewall.Gas is during through the volume separator, and objectionable impurities wherein, dirt etc. can be absorbed or filter out by water-soluble separating, and the volume separator also can be avoided the vavuum pump medium phenomenon of backflowing, and can guarantee the steady quality of product.
Description of drawings
Below in conjunction with accompanying drawing the vacuum extractor of a kind of plastic extruder of the utility model is done explanation in further detail;
